Neutrons in Material Science and Engineering — •Anke Rita Pyzalla — TU Wien, Institute of Material Science and Technology, 1040 Wien, Austria

Due to their high penetration depth in structural materials neutrons offer outstanding possibilities in material science and engineering. The physical methods used comprise diffractometry, small angle scattering and tomography. Neutron texture analyses are a unique means for determining the orientation distribution function of crystallites and thus are essential for optimizing the physical and mechanical properties of materials and components. Strain/stress analyses using neutron diffraction also play an important role in science and industry since detrimental internal stress state are often responsible for early and unexpected component failure. Neutron small angle scattering enables characterizations e.g. of precipitation states and particle sizes, which are a necessary link between material microstructure and material properties. Neutron tomography is unique for revealing inner structures of complex industrial components non-destructively. Examples for innovative applications of neutron diffraction, small angle scattering and tomography in material science and engineering will be given and an outlook on future possibilities arising at new instruments and upcoming sources will be presented.
